The TPI 265 digital clamp meter is an average-sensing, manual- and auto-ranging multimeter for measuring current, voltage, resistance, capacitance, and frequency in electrical testing applications. It has a clamp that measures AC current to 400 amp. The clamp has two jaws that can close around an electrical conductor up to 35mm (1.37") in diameter to measure current without touching or interrupting the circuit. A set of test leads is included for measuring AC and DC voltage to 600V, resistance to 40 megohms, voltage frequency to 40mHz (megahertz), and capacitance to 4,000 microfarads. An audible continuity sensor confirms that the circuit conducts electricity, and a diode check detects whether a circuit's diodes are working properly. To aid documentation of readings and capture readings in tight spaces, the data hold function keeps the most recent reading on the display after disconnecting from the circuit. The meter has a rotary switch to select the property to measure, and a 4,000-count LCD that shows readings numerically and in a 41-segment bar graph. The unit operates on a single 9V battery, and turns off automatically after 10 minutes of non-use to conserve battery life. It has a low-battery indicator that signals when the battery needs to be replaced. Clamp meters are typically used by electrical engineers to measure properties of electrical current without physically touching or disconnecting the conductor.This average-sensing, or average-responding, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. It has two ranging modes: manual, which allows the user to select the operating range, and auto, which automatically selects the appropriate operating range. Accuracy and resolution specifications vary according to the range being measured. It meets International Electrotechnical Commission (IEC) safety standard 61010 and is rated for CAT III installations to 600V, which covers items us...
